| Oct-26-18 | | Jambow: Not bad I couldn't find it but stockfish agrees with Fabiano. I'm wondering how often the very elite take a position like this examine it with an engine and then try to understand each move and the decisions that were used to get there. I say this because it seems to me that the top players moves are inline with engine moves more frequently. I believe this has more to do with higher ratings than the pool of new players at the bottom. My play showed noticeable improvement when I would go over elite players games and try to determine what their next move was, and if they made a move that made no sense to me I would pause examine and try to see what they were attempting to accomplish. Only when I just couldn't see it would I go on, and then go back over the moves again. I would think when you get in the 2700-2800 elo range silicon would be the next step after of course the greats of old and even recent. |

 | | al wazir: What happens after 38. Rh1 ?
If 38...Qd7, then 39. Qg1, and after 39...gxf4 40. Rxf4, I don't see a winning continuation for black. |

 | | agb2002: Black is one pawn down.
White threatens Nxd5.
The position of the white king suggests 35... Qxf5: A) 36.Kxf3 Qxh3
A.1) 37.Rh1 Rxf4+ 38.Qxf4 (38.Ke2 Qg4#) 38... Rxf4+ 39.Kxf4 Qg2 looks good for Black because of the activity of the black queen, the weak pawn on c2 and the possibility of attacking the white king with king, queen and two pawns. A.2) 37.Ke2 Qxg3 seems to win two pawns since the knight is lost (38.Nh5 Qg4+; 38.Nd5 Qe5+). B) 36.Re2 Nh4 37.Ke1 (37.gxh4 Qxf4+ wins decisive material) 37... Ng6, with the threat 38... Nxf4 39.gxf4 Qxh3 looks very good for Black. |

| Oct-26-18 | | thegoodanarchist: After 41.Rexf4, how does Black win?
I think it would be by 41...Rxf4, keeping the pin in place. White will be in zugzwang, and the Black king can come down the board. But I may be wrong.
By the way, Naiditsch's play was a little hinky in GRENKE. |

| Oct-26-18 | | RandomVisitor: <thegoodanarchist><After 41.Rexf4, how does Black win?> It looks like black just exchanges away on f3 - the resulting king and pawn ending is clearly a win for black, with the two kingside passers. |

<35....?>
I had the first move but didn't properly calculate the followup. Typically, as Black doesn't really gain anything from from taking on f5. <35....Qxf5 36.Kxf3> and I kinda thought Black was ok here because of the pin and the bad king position, and thought both Qxh3! and g5?! would do the job. <36....Qxh3!> does the job as it also pins Pg3 so Black's directly threatening Rxf4+ and a win. However, <36....g5?! 37.Kg2! ±<>> Black drops a pawn for no reason. |

You're partly right as RV correctly states. Basically White's down and out after 40....Rxf4: in fact, he is in a practical zugzwang already and leaves just 41.Rxf4: moving the King or Queen drops Rf3, moving the Rook to anything but f4 allows Rxf3 with pandemonium and if the pawns move Black can just play Qxf3+. 41.Rxf4 Rxf4 with similar zugzwang, and indeed Black just trades all pieces for the easiest win. |

| Oct-26-18 | | patzer2: For today's Friday puzzle, I got as far as 35. Qxf5 Kxf3 36. Qxh3 Re4 in attempting to solve it. But instead of the strongest follow-up 36...Qxg3! -+ (-2.94 @ 25 ply, Stockfish 9), I deviated with the premature piece capture 36...gxf4 ∓ (-1.04 @ 21 ply, Stockish 9). White's game takes a turn for the worse with 33. Kg1? Ref6 ∓ (-1.20 @ 25 ply, Stockfish 9). Instead, the first player can hold it near level with 33. Kh2 Ref6 34. g4 Nf6+ 35. Rxf3 Qxf3 36. Qf4 Qc6 37. Ng3 ⩱ (-0.30 @ 23 ply, Stockfish 9). As <RV> observes, <33. Kh2 likely draws>. Earlier, instead of improving Black's position with 14. Qb4?! b6 ⩱ (-0.46 @ 22 ply, Stockfish 9), White would have been better off with the straightforward 14. f4 ⩲ (+0.35 @ 21 ply, Stockfish 9). |

 | | Willber G: I chose 35...Rxf5 which wins at least the exchange, e.g. 36.Nxd5 Nxe1
37.Kxe1 Rxf1
38.Kd2 Rxc1
39.Kxc1 |
|
| Oct-26-18 | | Mendrys: <Willber G> A common foil to a lot of my failed combinations is that my opponent is not obligated to recapture in many cases. I didn't see your line but playing it through it seems that instead of 37. Kxe1 he can play 37. Nf4 and keeps his queen. The knight will fall eventually as he has no where to go. |
